BEFORE CARRYING OUT ANY OPERATION SUCH AS MAINTENANCE OR ADJUSTMENT
ON THE MACHINE, STOP THE TRACTOR ENGINE, REMOVE IGNITION KEY AND WAIT
FOR ROTATING DISCS AND ROTOR TO STOP COMPLETELY BEFORE LEAVING THE
TRACTOR.
BELT
Belt must be properly tensioned at all times to prevent
excessive slipping and flopping. A loose belt will cause
poor cutting and premature failures.
Check powerband tension as follows :
- Remove belt guard.
- Unlock counter-nut (E) (photo 47) and loosen belt (C)
(photo 48).
- Draw two marks on the belt (A), 1000 mm (39 1/3")
apart (photo 48).
- Tighten adjustment screw (D) (photo 47). Belt ten-
sion is correct when distance between marks (A) is
1007 mm (39 2/3").
- Retighten counter-nut (E) (photo 47) after the adjust-
ment has been made and refit the belt guard.
This precise adjustment should be made when a belt
is replaced and also when retensioning a belt
loosened for storage purposes.
A brief belt tension check should be made after the first
3 hours of use and periodically throughout the season.
To do so it is not necessary to remove the belt guard.
This check is made through the opening (F) located
above the guard after having removed the cover plate
(photo 48A).
Tension is correct when the belt does not deflect more
than 21 mm (4/5") when a force of 28 daN (60 lbs) is
applied mid-way between pulleys onto the whole width
of the belt.
Do not forget to replace the cover plate (P) (photo
48 A) after having made this check.
Note
: If damaged, replace the belt :
Part No. 831 116 77 for
FC 280 P
Part No. 831 116 78 for
FC 240 P
MAKE SURE BELT GUARD IS ALWAYS KEPT IN PLACE.
